Porous Zn-MOF with two diverse cages synthesized using functionalized biphenyl tricarboxylic acid: CO2 selective adsorption and fixation

A new MOF 1 shows a 3D porous framework formed by the interconnected dodecahedron and octahedron cages. Thus, the activated MOF 1 not only has excellent selective adsorption performance for C 2 H 2 , CO 2 and CH 4 , but also has good catalytic performance for the reaction of CO 2 fixation.
